Design
The NLC 2270 power supply is designed to supply argon-ion lasers with exacting power requirements in
order to maintain low noise operation and increase lifetimes. A number of features including Power
Factor Correction and Universal Input assure that variations in input voltages have no influence on laser
operation.
Compatibility
The 2270 is designed to efficiently run argon-ion lasers including many of our own lasers as well as
many of our competitor’s lasers. The power supply’s compact design and industry standard connections
allow for simple installation and guarantee backward compatibility.

CHAPTER 2
POWER SUPPLY SAFETY
PRECAUTIONS FOR SAFE OPERATION OF THE NLC 2270 POWER SUPPLY
1.
In the final installation, the mains primary signals and ELV secondary signals of the
“Mains”, “Laser”, and “Interface” connectors on the front panel must be isolated from the
operator and accessible by SELV circuits.
PRI
= Primary Reference (Hazardous)
ELV
= Extra Low Voltage
SELV = Safety Extra Low Voltage
2.
A minimum of an approved method of reinforced or double insulation must be between
any primary (PRI) hazardous and any extra low voltage (ELV) or safety extra low
voltage (SELV) source at the connectors of the power supply.
3.
Supplemental insulation is required between any ELV circuits and any user accessible
circuits.
4.
The electrical hazards of the power supply are the same as other electrical systems
connected to the AC power line. Only a qualified technician should install the power
supply. There are NO user serviceable parts within the power supply, therefore the
cover of the power supply and any connected component should never be opened, as
hazardous voltages may be present after the unit has been turned off.
REQUIRED MARKINGS
The following labels are found on the 2270 power supply. These labels can be used to identify potential
safety hazards.

CHAPTER 3
NLC 2270 PRODUCT LINE
This chapter contains information on the installation and operation of the National Laser Company (NLC)
2270 power supply. Information regarding the specifications of the power supply will also be given in
this chapter. Figure 3.1 shows the NLC 2270 power supply.
Figure 3.1 The NLC 2270 Power Supply
COOLING
The 2270 power supply is air-cooled. A fan draws cooling in at the rear of the power supply and
exhausts warm air through the side vents. As mentioned in the "MOUNTING" section below, you will
need to provide adequate space for air intake at the sides of the power supply and exhaust through the
fan at the rear of the power supply, and must prevent heated exhaust air from returning to the intake.
HANDLING AND SHIPPING
When unpacking and carrying any power supply, lift it by the center, and not by the cord.
We recommend storing the container in which the 2270 power supply was shipped for future use. The
container was specially designed to cushion laser equipment and prevent damage during shipment. If
you need to return the power supply for service, the specially designed container will provide adequate
protection.
Page 4
MOUNTING
Allow clearance for air intake at the rear and air exhaust at the sides of the 2270 power supply.
Mounting dimensions for the power supplies are shown on the "Layout Drawing" at the end of this
chapter.

Table 3.2 Remote Interface Pin Connections for the NLC 2270 Power Supply
*These pins are digital inputs. Each input has a “pull up” resister to the internal +15 vdc buss. A logic
‘1’ (high) is “open circuit” or between +12 and +15 vdc. A logic ‘0’ (low) is “shorted” to GROUND or
between 0 and +3 vdc. These inputs are compatible with “open collector” TTL outputs or CMOS
outputs (when CMOS gates are operated from a +15 vdc supply), mechanical switches and relay
contacts. However, they are most typically operated in a “hard wired” condition using manually placed
shorting jumpers.
Page 7
The power supply should never be energized unless the laser head is connected. Make sure that the
key and rocker switch are turned to their off positions before making any connections.
Plug the umbilical cables from the laser head into the umbilical connectors (these connectors are
marked "LASER") on the power supply. Make sure the locking ring is secure on the left connector and
that the right connector is securely attached.
OPTIONAL REMOTE CONTROL
The 2270 power supply is available with an optional remote control. The model 1000 and 2000 remote
controllers allow the user to monitor and control output power and laser current. The model 1000
remote controller is compatible with power supplies that are running lasers rated for <100mW output
power. The model 2000 remote controller is compatible with power supplies that are running lasers
rated for >100mW output power. A remote stand is also available for more simplified operation. Remote
controls include a plug for remote interlock purposes.

REMOTE CONTROL OPERATION
Discharge switch - Must be in the ON position for the laser to emit light.
Emission LED - will be illuminated when the Mains Power switch is in the on position indicating
possible laser radiation
Run/Standby switch - selects either run or standby mode. Run mode allows the current/output
power to be adjusted with the Level Adjust knob. In Standby mode the laser runs at minimum
current/output power.
Page 8
Light/Current switch - selects either current or light mode. Light mode regulates the laser
output power. Current mode runs the laser at a constant current.
Level Adjust knob - sets the output power when running in the Light mode, sets the laser
current when running in Current mode (see Light/Current switch).
Display - displays tube current or laser output power in mW depending on the position of the
Meter switch.
Meter switch - selects either Power (mW) or Current (Amps) to display.
Remote Interlock - This connector is to complete the remote interlock circuit. The LED will be
illuminated if the interlock is complete.
